Tetrosomus

Tetrosomus is a genus of marine ray-finned fishes belonging to the family Ostraciidae, the boxfishes. The fishes in this genus are known as turretfishes and they are found in the Indian and western Pacific Oceans.

==Taxonomy== Tetrosomus was first proposed as a monospecific genus in 1839 by William Swainson with Ostracion turritus as its type species by monotypy. O. turritus was first formally described in 1775 by the Finland-born Swedish explorer, orientalist, naturalist Peter Forsskål with its type locality given as the Red Sea off Mokha in Yemen. O. turritus is now considered to be a junior synonym of O. gibbosus which had been described by Carl Linnaeus in the 10th edition of Systema Naturae published in 1758. The 5th edition of Fishes of the World classifies this genus within the family Ostraciidae in the suborder Ostracioidea within the order Tetraodontiformes.
